These are the immigrants from Asia, Africa and South America, the less powerful continents of the world, in terms of finance and geopolitics. These immigrant laborers are paid very low wages and have been reported to become victims of human rights violations many times, in the USA. The companies who employ them have also been accused of being insensitive to environmental concerns as much as they are to humanitarian concerns. This study is an attempt to find the root causes of the immigration problem by linking these two aspects based on a paradigm of sustainable development.Especially, the immigrants from South America have been employed in huge numbers by the multi-national companies which have ventured into mining, farming and railroad industry in the USA (Sheppard and Barnes, 294). What is the factor that made people from the developing world of South America to immigrate to USA (even illegally) facing risks even to their lives and why do they opt for the lower paid jobs and discriminatory existence in an alien land, is the primary question that has to be addressed in this regard. The one and only logical answer to this question are that they had been deprived of their livelihoods in their native lands. And the cause of this phenomenon easily connects back to the intervention of the US capital in these countries, as will be made clear in the following part of this study. The companies who employ the immigrant workers in the USA have a notorious history of exploiting nature and human resources (Cooke, 52).
